Victoria is an electric heat primary with some gas and oil too. 200 is pretty much the standard service size but few are over 60 amps of calculated load.
On the 75 KVA pole top transformer are 3 skinny houses, a duplex and a triplex. I think there is a 5 plex on it too but not certain the service to that building is from the back or the front. BC hydro sized resi services by the heat load and pretty much ignores the rest.
The 3 skinny houses are 100's the duplex and the triplex are 200. all Have electric heat and some split with gas. The utlity says the 75 KVA transformer can run %100 overload for 6 to 12 hours. I think they drop #1 or #2 aluminum for a 200 amp service and 266 for a 400 amp
